Publication number: 20180222465Abstract: A control valve for an automatic parking brake having an inlet for coupling to a source a brake pipe pressure, an outlet for coupling to a control inlet of the automatic parking brake and a pilot for coupling to the source of brake pipe pressure. The control valve is moveable between a first position where the inlet is in communication with the outlet and a second position where the inlet and the outlet are isolated from each other in response to a predetermined amount of brake pipe pressure at the pilot. The control valve includes a spring biasing the control valve into the first position.Type: ApplicationFiled: February 7, 2017Publication date: August 9, 2018Applicant: New York Air Brake, LLCInventor: Derick Call

Patent number: 10011289Abstract: A locking mechanism for a brake cylinder that has a tube surrounding the hollow shaft of the brake cylinder with a first set of teeth formed along an outer surface thereof. A gate having a second set of teeth corresponding to the first set of teeth is moveable in between a first position, wherein the first and second set of teeth are engaged to prevent movement of the brake cylinder piston, and a second position where the first and second set of teeth are disengaged to allow movement of the brake cylinder piston. A spring biases the gate into the locked position and a supplemental piston responsive to a source of brake pipe pressure can move the gate into the unlocked position so that the main piston is free to move.Type: GrantFiled: November 21, 2016Date of Patent: July 3, 2018Assignee: New York Air Brake, LLCInventors: Derick Call, Justin LaCosse, Craig Floyd Hughes, James Lewis Vendlinski

Publication number: 20180079401Abstract: An electronically controlled pneumatic (ECP) overlay control valve can selective switch between a conventional pneumatic mode and an ECP mode. In ECP mode, the overlay control valve shunts the brake cylinder pressure of the pneumatic control valve which allows a relay valve to build or exhaust pressure in the brake cylinder in response to an electronically controlled apply/release circuit. In conventional pneumatic mode, the overlay control valve disconnects the relay valve and allows a conventional pneumatic control valve to control the pressurization and exhausting of the brake cylinder.Type: ApplicationFiled: September 22, 2016Publication date: March 22, 2018Applicant: NEW YORK AIR BRAKE, LLCInventors: Keith Parnapy, Derick Call

Patent number: 9789889Abstract: A slack adjuster for narrow gauge rail cars including a housing having a body with a first clevis joint, a coupling secured to the body, and a guide tube secured to the body coupling. A lever is pivotally coupled to the housing for moving an actuator coupled to a clutch. The clutch is engaged with the external threads of a rod and moveable between a first captured position, a second position where the clutch is free to rotate, and a second captured position to selectively control movement of the rod. Movement of the lever withdraws the actuator so that the clutch releases and can spin, allowing the threaded rod to translate from the retracted to extended positions. Opposing forces applied to a ram causes the clutch to move to the second captured position, thereby preventing rotation of the clutch and preventing the threaded rod from retracting further into the housing.Type: GrantFiled: October 24, 2014Date of Patent: October 17, 2017Assignee: New York Air Brake, LLCInventors: Brian Graves, Jeffrey Sauter, Derick Call, James Brierley

Publication number: 20160114776Abstract: A brake cylinder maintaining system that combines a brake cylinder maintaining check valve and a quick service limiting valve into a single unit to have lower hysteresis, and thus more precise BCM regulation pressure and a smaller pressure offset. The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.Type: ApplicationFiled: October 24, 2014Publication date: April 28, 2016Inventors: Derick Call, Howard E. Huber, JR., Brian Graves

Patent number: 9266516Abstract: A brake cylinder maintaining valve may include spool valves or poppet valves. When the pressure in the brake cylinder drops below its original set pressure, such a maintaining valve may feed brake pipe (BP) pressure through a choke to replenish and maintain brake cylinder (BC) pressure up to a certain point. If the leak is too great, such as when it exceeds the capacity of the choke, the brake cylinder pressure will not be maintained. Such a maintaining valve may be either integrated into the control valve, or it may be mounted remotely to the brake system. If mounted remotely, it may be connected by multiple ways, including through a conventional 4-port access plate.Type: GrantFiled: September 27, 2013Date of Patent: February 23, 2016Assignee: New York Air Brake, LLCInventors: Derick Call, Jason Connell, Steven R. Newton

Patent number: 9180853Abstract: In a rail vehicle hand brake having a release activated by a pneumatic cylinder, the present control system includes a manual valve having an output connected to a source of pressure at an input when manually activated. A volume is to be charged by the source of pressure. A choke connects the volume to exhaust. The volume and the choke prolong the time the source of pressure is connected to the pneumatic cylinder after the manual valve is activated.Type: GrantFiled: June 11, 2014Date of Patent: November 10, 2015Assignee: New York Air Brake LLCInventors: Derick Call, Steven R. Newton, Lawrence E. Vaughn, Jeffrey F. Sauter, Howard E. Huber, Jr.
